200 THE ENTOMOLOGIST. 



V. Urticae, earliest, March 24 ; latest, June 27 (disappearing 

 the whole of May). V. Polychloros, earliest, March 28; 

 latest, May 2. Pieris Brassicae, earliest, April 7 ; latest, 

 June 27. P. Rapae, earliest, April 20; latest, June 27. 

 P. Napi, earliest, April 25 ; latest, June 9. Anthocharis 

 Cardamines, earliest, April 29 ; latest, June 9. 



The remaining five species were only seen once each ; and 

 of the ten, previously mentioned, I noticed five during the 

 first fortnight in July, namely, — Pieris Brassicae, P. Rapae, 

 P. Napi, Vanessa Urticse, and Satyrus Janira, as well as two 

 additional species that I had not observed from March to 

 June inclusive, — Satyrus Hyperanthus, Julv 3 and 4, and 

 Thecla W-Album, July 10. 



From the foregoing statistics it will be perceived that of 

 the above fifteen species, so far at any rate as my own 

 observation went, Gonepteryx Rhamni (male) was the earliest 

 seen, on the 18th of March, and Polyommatus Alexis and 

 Pamphila Sylvanus the two latest, on the 9th of June. That 

 the two kinds, moreover, most frequently noticed, were Pieris 

 Rapae, seen on twenty-three days, and P. Brassicae, on nine- 

 teen ; next to these, Vanessa Urticae and Gonepteryx Rhamni, 

 seen respectively on fourteen days; and next, Pieris Napi, 

 Anthocharis Cardamines, and Vanessa lo, which were each 

 observed on twelve days. Also that of the tribe of whites, 

 which, as regards the number of individual specimens, do 

 not appear to be particularly numerous this season, Brassicae 

 occurred nearly a fortnight before Rapae, more than a fort- 

 night before Napi, and three weeks before Cardamines; that 

 Rapae was seen five days before Napi, and Napi in its turn 

 four days before Cardamines; that the earliest Satyrid 

 (P. Egeria) was observed nearly a month previous to any of its 

 congeners, on the 23rd of April, later than two species of 

 Pieridae, Brassicae, and Rapae, and earlier than another two, 

 Napi and Cardamines; that the three remaining species of 

 Satyridae were later than the two latest species of Pieridae ; 

 that Megaera occurred ten days before Pamphilus, and thirty 

 days before Janira; that Pamphilus and Egeria were only 

 seen once each, but Janira and Megaera seven times in each 

 case, — the appearances of Janira, however, being restricted to 

 June, and Megaera, on the other hand, ranging over the two 

 mouths, May and June, being noticed three times in the
